PREFACE TO PART FIRST.

In a systematic course of general education, Arithmetic claims a place among the primary objects. Its elementary exercises, when rationally conducted, are adapted to the capacities of children at a very early age. Its influence on the character of children, in developing the reasoning faculties, and habituating the mind to investigation, highly conducive to progress in every other branch of knowledge. Notwithstanding the obvious truth of the above remark, the practice of postponing arithmetic tili pupils arrive at the age of nine or ten years, still prevails in a great part of our country, and calls for the attention of those, to whom the concerns of popular education are intrusted.

The purpose of this Manual is, to facilitate the instruction of the younger classes in common schools. It contains the first part of a Course of Exercises in Arithmetic, which is to be published in three parts. The plan of the lessons accords with the method of instruction practised in the school at Stantz, by the celebrated Pestalozzi. The method of illustration, by the use of cuts, and the location of unit marks under questions, it is hoped, will be found to be an improvement.

PART FIRST has been confined to the simple elements of arithmetic, with a view of rendering it a suitable introduction to the subsequent study of the science from books, which are already in use, and which are thought to be deficient in elementary exercises.

The slate and pencil are not required, in the performance of the lessons contained in Part First. On the title page, will be seen, a drawing of an improved structure of the Abacus. It is a convenient apparatus for illustrating the combinations of numbers, and may be used in connexion with these lessons, although it is not indispensable.

Boston, August 20, 1829.
